The initiative is taken by diamond brand, Diya Diamond, for which the 29-year-old actress is the brand ambassador.
The former Miss India, who is also an active gay rights activist, feels the tree plantation initiative has the power to become an agent of change in support of sustainable and equitable development.
"The activity is the perfect platform to create awareness about our environmental issues and a step in the right direction. I hope everybody joins us and takes a pledge to give back to nature and become proactively environmentally friendly," said Celina who has worked in movies like "Golmaal Returns" and "Hello darling".
